Collpas: Activity Hotspots For Frugivorous Bats (Phyllostomidae) In The Peruvian Amazon, Adriana Bravo, Kyle E. Harms, Richard D. Stevens, Louise H. Emmons

Faculty Publications

In the SE Peruvian Amazon, large numbers of frugivorous bats regularly visit natural forest clearings known locally as collpas (which are also referred to as clay licks or mineral licks). Bats arrive at collpas to drink water that has accumulated in depressions created by larger geophagous mammals that consume exposed soil. Although collpa visitation is common, little is known about its causes and its ecological implications for the bat community. We compared patterns of use of collpas and non-collpa forest sites by bats in SE Peru. We mist netted bats at collpas and non-collpa sites during the dry season and …

Globally Optimal Grouping For Symmetric Closed Boundaries By Combining Boundary And Region Information, Joachim S. Stahl, Song Wang

Faculty Publications

Many natural and man-made structures have a boundary that shows a certain level of bilateral symmetry, a property that plays an important role in both human and computer vision. In this paper, we present a new grouping method for detecting closed boundaries with symmetry. We first construct a new type of grouping token in the form of symmetric trapezoids by pairing line segments detected from the image. A closed boundary can then be achieved by connecting some trapezoids with a sequence of gap-filling quadrilaterals. For such a closed boundary, we define a unified grouping cost function in a ratio form: …

Ant Clustering With Locally Weighting Ant Perception And Diversified Memory, Gilbert L. Peterson, Christopher B. Mayer, Thomas L. Kubler

Faculty Publications

Ant clustering algorithms are a robust and flexible tool for clustering data that have produced some promising results. This paper introduces two improvements that can be incorporated into any ant clustering algorithm: kernel function similarity weights and a similarity memory model replacement scheme. A kernel function weights objects within an ant’s neighborhood according to the object distance and provides an alternate interpretation of the similarity of objects in an ant’s neighborhood. Ants can hill-climb the kernel gradients as they look for a suitable place to drop a carried object. The similarity memory model equips ants with a small memory consisting …

Money Or Nothing: The Adverse Environmental Consequences Of Uncompensated Land Use Controls, Jonathan H. Adler

Faculty Publications

The conventional wisdom holds that requiring compensation for environmental land use controls would severely limit environmental protection efforts. There are increasing reasons to question this assumption. Both economic theory and recent empirical research--focused primarily on the Endangered Species Act but potentially applicable to other environmental regulations that create similar incentives--demonstrate that failing to compensate private landowners for the costs of regulation discourages voluntary conservation efforts and can encourage the destruction of environmental resources. The lack of a compensation requirement also means that land use regulation is "underpriced" as compared to other environmental protection measures for which government agencies must pay. …

Imprinting Of An Evolutionarily Conserved Antisense Transcript Gene Apeg3, Jung Ha Choo, Jeong Do Kim, Joomyeong Kim

Faculty Publications

APeg3 is an antisense transcript gene of Peg3, which has been recently identified from rat brain. Careful analyses of EST databases indicated that a homologous transcript also exists in other mammalian species, including mouse, cow and human. 5′-and 3′-RACE experiments have subsequently identified a 900-bp cDNA sequence of APeg3 from mouse brain. Mouse APeg3 is localized in the 3′UTR of Peg3 with an intronless genomic structure. The expression of mouse APeg3 is derived mainly from the paternal allele, indicating the imprinting of this antisense transcript gene in brain. Strand-specific RNA analyses also revealed the expression of both human and cow …

Origin Of The Eastern Brownsnake, Pseudonaja Textilis (Duméril, Bibron And Duméril) (Serpentes: Elapidae: Hydrophiinae) In New Guinea: Evidence Of Multiple Dispersals From Australia, And Comments On The Status Of Pseudonaja Textilis Pughi Hoser 2003, David J. Williams, Mark O'Shea, Roland L. Daguerre, Catharine E. Pook, Wolfgang Wüster, Christopher J. Hayden, John D. Mcvay, Owen Paiva, Teatu Lohi Matainaho, Kenneth D. Winkel, Christopher C. Austin

Faculty Publications

Pseudonaja textilis is a widespread and common snake in eastern parts of Australia, but its distribution in New Guinea is poorly understood, and the origin of the New Guinea populations and its timing have been the subject of much speculation. Phylogenetic analysis of mitochondrial DNA sequences from three New Guinea populations of P. textilis indicates that New Guinea was colonised from two independent eastern and western migration routes most likely in the Pleistocene. One dispersal event from northern Queensland led to the populations in eastern New Guinea (Milne Bay, Oro and Central Provinces, Papua New Guinea), whereas another, from Arnhem …

Ozone Exposure In A Mouse Model Induces Airway Hyperreactivity That Requires The Presence Of Natural Killer T Cells And Il-17, Paul B. Savage, Muriel Pichavant, Sho Goya, Everett H. Meyer, Richard A. Johnston, Hye Y. Kim, Ponpan Matangkasombut, Ming Zhu, Yoichiro Iwakura, Rosemarie H. Dekruyff, Stephanie A. Shore, Dale T. Umetsu

Faculty Publications

Exposure to ozone, which is a major component of air pollution, induces a form of asthma that occurs in the absence of adaptive immunity. Although ozone-induced asthma is characterized by airway neutrophilia, and not eosinophilia, it is nevertheless associated with airway hyperreactivity (AHR), which is a cardinal feature of asthma. Because AHR induced by allergens requires the presence of natural killer T (NKT) cells, we asked whether ozone-induced AHR had similar requirements. We found that repeated exposure of wild-type (WT) mice to ozone induced severe AHR associated with an increase in airway NKT cells, neutrophils, and macrophages. Surprisingly, NKT cell-deficient …

Novel Role Of Antioxidant-1 (Atox1) As A Copper-Dependent Transcription Factor Involved In Cell Proliferation, S. Itoh, H. W. Kim, O. Nakagawa, K. Ozumi, Susan M. Lessner, H. Aoki, K. Akram, R. D. Mckinney, M. Ushio-Fukai, T. Fukai

Faculty Publications

Copper plays a fundamental role in regulating cell growth. Many types of human cancer tissues have higher copper levels than normal tissues. Copper can also induce gene expression. However, transcription factors that mediate copper-induced cell proliferation have not been identified in mammals. Here we show that antioxidant-1 (Atox1), previously appreciated as a copper chaperone, represents a novel copper-dependent transcription factor that mediates copper-induced cell proliferation. Stimulation of mouse embryonic fibroblasts (MEFs) with copper markedly increased cell proliferation, cyclin D1 expression, and entry into S phase, which were completely abolished in Atox1^-/- MEFs. Promoter analysis and EMSA revealed that copper …

In Vivo Yy1 Knockdown Effects On Genomic Imprinting, Joomyeong Kim, Jeong Do Kim

Faculty Publications

The YY1 transcription factor is predicted to control several imprinted domains, including the Peg3, Gnas and Xist/Tsix regions. To test this possibility, we have used RNA interference strategies to generate transgenic mouse lines that express reduced levels of the cellular YY1 protein. As predicted, lowering YY1 levels resulted in global expression changes in these three imprinted domains. In neonatal brains, most imprinted genes of the Peg3 domain were up-regulated. In the Gnas domain, Nespas was down-regulated, whereas three other imprinted transcripts were up-regulated, including Nesp, Gnasxl and Exon1A. In the Xist/Tsix domain, no obvious change was detected in the expression …

Interactions Between Bacterial Carbon Monoxide And Hydrogen Consumption And Plant Development On Recent Volcanic Deposits, Gary M. King, Carolyn F. Weber

Faculty Publications

Patterns of microbial colonization and interactions between microbial processes and vascular plants on volcanic deposits have received little attention. Previous reports have shown that atmospheric CO and hydrogen contribute significantly to microbial metabolism on Kilauea volcano (Hawaii) deposits with varied ages and successional development. Relationships between CO oxidation and plant communities were not clear, however, since deposit age and vegetation status covaried. To determine plant-microbe interactions in deposits of uniform ages, CO and hydrogen dynamics have been assayed for unvegetated tephra on a 1959 deposit at Puu Puai (PP-bare), at the edge of tree islands within the PP deposit (PP-edge) …

Cellular Uptake And Lysosomal Delivery Of Galactocerebrosidase Tagged With The Hiv Tat Protein Transduction Domain, Xian Yang Zhang, Annie Dinh, James Cronin, Su Chen Li, Jakob Reiser

Faculty Publications

A number of studies have shown that a short peptide, the protein transduction domain (PTD) derived from the HIV-1 Tat protein (Tat-PTD) improved cellular uptake in vitro and distribution in vivo of recombinant proteins bearing such PTDs when administered systemically. To investigate the effects of Tat-PTD addition on the subcellular localization of the lysosomal enzyme galactocerebrosidase (GALC, EC 3.2.2.46) and with a view towards designing improved therapeutic strategies for Krabbe disease (globoid cell leukodystrophy), mouse GALC was tagged C-terminally with the Tat-PTD. Compared with unmodified GALC, GALC bearing a Tat-PTD, a myc epitope and 6 consecutive His residues [GALC-TMH (Tat-PTD, …

Effects Of Cyclic Hypoxia On Gene Expression And Reproduction In A Grass Shrimp, Palaemonetes Pugio, Nancy J. Brown-Peterson, C. Steve Manning, Vishal Patel, Nancy D. Denslow, Marius Brouwer

Faculty Publications

Cyclic changes in dissolved oxygen occur naturally in shallow estuarine systems, yet little is known about the adaptations and responses of estuarine organisms to cyclic hypoxia. Here we examine the responses of Palaemonetes pugio, a species of grass shrimp, to cyclic hypoxia (1.5-8 mg/l dissolved oxygen; 4.20-22.42 kPa) at both the molecular and organismal levels. We measured alterations in gene expression in hepatopancreas tissue of female grass shrimp using custom cDNA macroarrays. After short-term (3-d) exposure to cyclic hypoxia, mitochondrial manganese superoxide dismutase (MnSOD) was upregulated and 70-kd heat shock proteins (HSP70) were downregulated. After 7-d exposure, nuclear genes encoding …

Expression And Evolutionary Relationships Of The Chenopodium Quinoa 11s Seed Storage Protein Gene, Mikel Stevens, Peter J. Maughan, Daniel J. Fairbanks, Marie R. B. Balzotti, Jennifer N. Thornton, David A. Mcclellan, Eric N. Jellen, Craig E. Coleman

Faculty Publications

Quinoa (Chenopodium quinoa Willd.) is a food crop cultivated by subsistence farmers and commercial growers on the high Andean plateau, primarily in Bolivia, Peru, and Chile. Present interest in quinoa is due to its tolerance of harsh environments and its nutritional value. It is thought that the seed storage proteins of quinoa, particularly the 11S globulins and 2S albumins, are responsible for the relatively high protein content and ideal amino acid balance of the quinoa seed. Here we report the genomic and cDNA sequences for two 11S genes representing two orthologous loci from the quinoa genome. Important features of the …

Federalism, The Rehnquist Court, And The Modern Republican Party, Bradley W. Joondeph

Faculty Publications

Most scholars agree that federalism was central to the Rehnquist Court's constitutional agenda. But there is a part of the federalism story that has been largely overlooked: the Court's decisions involving the structural constraints on state governments, the most significant of which are preemption and the dormant Commerce Clause. This article makes two empirical claims about the Rehnquist Court's federalism jurisprudence, one descriptive and one interpretive. The descriptive claim is that that the Court's overall approach to federalism was more complicated than many have assumed, and it was not necessarily friendly to the states. To support this contention, I present …

Envious Enemies Of The Cross Of Christ (Philippians 3:18), David E. Fredrickson

Faculty Publications

Contrary to the common understanding, the “enemies of the cross of Christ” in Phil 3:18 are the same people who “proclaim Christ from envy and rivalry” in 1:15. These “enemies” want Paul’s fame, but not the suffering that is built into loving.

My Sinful Self: The Self As Enemy, Steven D. Paulson

Denaturing Gradient Gel Electrophoresis As A Tool To Determine Batch Similarity Of Probiotic Cultures Of Porcine Cecal Bacteria, Michael Hume, Charles M. Scanlan, Roger B. Harvey, Kathleen Andrews, James D. Snodgrass, Armen Nalian, Alexandra Martynova-Van Kley, David Nisbet

Faculty Publications

A continuous-flow porcine cecal bacterial culture has been used experimentally as treatment against enterotoxigenic Escherichia coli in weanling pigs. Periodically, the cultures must be started from frozen stock. Our results indicate that denaturing gradient gel electrophoresis can be applied as an indirect indication of culture similarity for each new batch generated from frozen stock.

Sexual Selection And Alternative Reproductive Tactics In Cyprinodon Elegans, Jennifer M. Gumm

Faculty Publications

In systems with alternative reproductive tactics (ARTs), males have discrete behaviors and morphologies that allow them to optimize their reproductive success in relation to others in the population. Males with different phenotypes directly compete with one another for mates, providing unique opportunities for studying social interactions within a species. Using the Comanche Springs pupfish, Cyprinodonelegans, a species with three alternative reproductive tactics, I examine how male behaviors and social interactions influence the reproductive success of each tactic.

Previous studies suggest that large territorial males have high reproductive success, while satellite males and female mimics must intrude into territories in order …

A Question Of Progress And Welfare: The Jitney Bus Phenomenon In Atlanta, 1915-1925, Julian C. Chambliss

Faculty Publications

The article focuses on the popularity of private buses modified for passenger service known as jitneys in Atlanta, Georgia as alternatives to streetcars from 1915 to 1925. Jitneys were originated from Los Angeles, California in 1914 and became a success in Atlanta because of their low fares and convenience. Complaints are also listed in response to the venture, citing streetcar companies and city officials urging regulation of jitneys due to their competitive pressure. Commentary is also given noting the social class conflict which was manifested in the transportation policy debate.

Freeriders And Diversity In The Legal Academy: A New Dirty Dozen List, Ediberto Román, Christopher B. Carbot

Faculty Publications

Latina and Latino student enrollment in U.S. law schools the last few decades has increased. This increase, however, has not resulted in a comparable increase in Latino and Latina law professors. To foster diversity in law school faculties and to increase Latina representation, the “Dirty Dozen List” was published. The List was comprised of the top twelve U.S. law schools located in high Latina populated areas but lacking a single Latina professor on the faculty. The List served to increase awareness of the lack of diversity at some of the nation’s top legal institutions, as well as “shame” these schools …

Juvenile-To-Adult Antler Development In White-Tailed Deer In South Texas, James Kroll, Ben Koerth

Faculty Publications

Past studies using penned deer provide conflicting results on the age when reliable predictions about antler growth potential in white-tailed deer (Odocoileus virginianus) can be made. We captured wild whitetail males via aerial net gun on 12 ranches in 5 counties in south Texas, USA, from 1999 to 2007 to determine if a reliable juvenile-to-adult relationship in antler development existed. We individually marked and released captured animals at the trap site after we took antler and body measurements. We recaptured marked animals as possible in subsequent years or until we obtained final measurements after legal harvest. Amount of growth in …

Estimating Bobcat Abundance In East Texas Using Infrared-Triggered Cameras, Matthew E. Symmank, Christopher E. Comer, James C. Kroll

Faculty Publications

Reliable population estimation techniques for cryptic forest predators generally are lacking. Development of an efficient and reliable technique to estimate predator abundance directly would be a valuable tool for wildlife managers concerned with predator management. We evaluated the potential for camera survey techniques to provide abundance estimates for bobcats (Lynx rufus) in southeastern forest habitats. We also determined our ability to capture other forest carnivores photographically using these techniques. We used TrailMaster 1500 active infrared-triggered cameras to estimate abundance on a 1318-ha private land holding in eastern Texas. Camera stations were located along roads and wildlife travel corridors …

Bmp Signaling Goes Posttranscriptional In A Microrna Sort Of Way, Catherine A. Reinke, Richard W. Carthew

Faculty Publications

Aberrant microRNA (miRNA) expression correlates with human diseases such as cardiac disorders and cancer. Treatment of such disorders using miRNA-targeted therapeutics requires a thorough understanding of miRNA regulation in vivo. A recent paper in Nature by Davis et al. expands our understanding of miRNA biogenesis and maturation, elucidating a mechanism by which extracellular signaling directs cell differentiation via posttranscriptional regulation of miRNA expression.

The Name Is The Same, But The Facts Have Been Changed To Protect The Attorneys: Strickland, Judicial Discretion, And Appellate Decision-Making, Gregory J. O'Meara

Faculty Publications

The gap between historical events and the way courts recount them in appellate decisions is highlighted by the differences in fact descriptions offered in the same case: Strickland v. Washington. The Supreme Court's majority decision ignores or recasts facts found in the lower courts in this case.

Paul Ricoeur, the leading philosopher of narrative, provides a framework that explains how legal facts are malleable and subject to distortion in his work on non-fiction narratives. He lays out instabilities inherent in any use of language and then broadens his inquiry to show that the transition from the oral to the written …

The Rhetoric Of Self-Defense, Janine Young Kim

Faculty Publications

The rhetoric of self-defense is a powerful instrument in the hands of legal actors to shape our understanding of justified violence in society. This rhetoric is based not in the legal definition of self-defense but rather in the paradigmatic situation of deadly response to deadly attack, which offers useful guidance in interpreting the law's required elements. However, the paradigm also tends to embrace claims of morality and right that threaten to expand self-defense beyond recognition to consider inappropriate values such as vengeance and punishment.

In this Article, the author argues that self-defense should be viewed not only as a moral …

The 60th Anniversary Of The Everson Decision And America's Church-State Proposition, Carl H. Esbeck

Faculty Publications

Sixty years ago the U.S. Supreme Court handed down Everson v. Board of Education of Ewing Township, which for the first time incorporated the Establishment Clause through the Fourteenth Amendment and made it binding on state and local governments. The case marks the beginning of the Court's modern era with respect to church-state relations. In Everson, the Justices said that the restraints on federal power represented by the Establishment Clause were the same as the ideas that emerged from the disestablishment struggles in the several states, with special attention to the Virginia experience. The disestablishment effort in the states, which …
